89410A A.09.05 firmware

Are there any known issues with this version?have 89410A sn 3416A01627 and attempted update from A.09.04, took the first disk, prompted me for the second and that was all she wrote. ROM Checksum failures abound.Option load AYB/AYA/AYH/B7A/AY7/AY9/UFG

Cancel that, I understand now why the manufacturer that made my 3.5" floppy disks did not put his name on them, for each of the 2 batches of 3 disks I made one of them was bad, mixed & matched and got it done.
